I have the Pfaff 2044 & I love it. I bought it new 13 years ago & have sewn miles on it. The IDT (walking foot) is a little black lever behind the needle that you pull down & forward to lock into place when you want to engage it. The thing I love about their IDT system is you can use different feet with the walking foot. The throat space on the machine is not very large for machine quilting. I do have a second machine with a larger throat space for quilting bigger quilts, but my 2044 is my go to machine for all of my piecing & general sewing. Feel free to pm me with any questions.
